Jobs Fullstack

Adwisely is an Ad Tech SaaS on Shopify that helps e-commerce businesses run ads on Meta and Google. We're evolving from a setup wizard into an AI that analyzes a store, identifies the best product opportunities, generates creatives, launches campaigns, and optimizes them automatically. The merchant sets a ROAS target and Adwisely does the rest.

We're looking for a senior engineer to take real ownership of the product and help us ship the next chapter.

What you'll own

In the first months, you'll get deep into the existing platform: stabilize, maintain, and build context. Then you'll move into building:

• AI-native experience. Store intelligence that analyzes a merchant's data, scores products by predicted ROAS, and drives every campaign decision automatically.
• Shopify-deep integration. Adwisely should live where merchants already work: Shopify admin, Sidekick, Flow, not as a separate tool they have to visit.
• Platform reliability and UX improvements. Bulletproof onboarding, ROAS optimisation, clearer performance visibility.
• Quality at every stage. You own QA as part of the delivery process. That means writing specs that include acceptance criteria, reviewing AI-generated code critically before merging, and making sure each feature is tested before it ships.

How we work

We build with AI-assisted development. The workflow is: write a tight spec, generate the implementation, review and refine, ship. You don't need to write every line from scratch. You need to spec well, review confidently, and maintain a high bar for what gets merged.

You'll work directly with the company founders. No PM layer, no sprint ceremonies.

Requirements

• 5+ years with Python and React in production
• Hands-on experience with AWS: EC2, RDS, S3, Lambda, or similar
• Comfortable owning the full stack: React frontend, Python backend, cloud infrastructure
• Experience with at least one of: Shopify APIs, Meta Marketing API, Google Ads API
• Used to being the primary engineer and making architectural calls without a lot of hand-holding
• Experience with AI coding tools (Cursor, Claude Code, Copilot)
• QA as part of shipping: you write tests, review diffs carefully, and don't consider something done until it's verified

Nice to have

• Experience building or maintaining Shopify apps
• Familiarity with LLM API integration (OpenAI, Gemini)
• Background in ad tech or performance marketing

What we offer

• Real equity: joining as the primary engineer at a pivotal moment
• Architecture ownership: meaningful decisions, not just tickets
• Fully remote, flexible schedule
• Competitive salary
• Paid vacation

Role Overview
We are looking for a highly capable Full Stack Engineer with deep experience in Python and React who is also very comfortable with harness engineering—building the surrounding tooling, automation, testing scaffolding, execution environments, and orchestration layers that allow systems, agents, workflows, and product features to be developed, validated, and run reliably at scale.

This role is ideal for an engineer who can move fluidly between backend services, frontend product development, automation frameworks, integration layers, and developer tooling. You should be equally comfortable shipping user-facing features and building the technical harnesses that make systems testable, observable, repeatable, and production-ready.

Key Responsibilities

• Build and maintain full stack applications using Python on the backend and React on the frontend.
• Design and implement APIs, services, and orchestration layers for product workflows and internal tools.
• Develop harnesses for testing, simulation, validation, execution, and monitoring of complex workflows, agents, or integrations.
• Create reusable frameworks for:
  • workflow execution
  • automated test runs
  • sandboxed environments
  • synthetic data generation
  • scenario replay
  • regression validation
• Build developer-facing tools to improve engineering velocity, quality, and repeatability.
• Integrate external services, APIs, and third-party tools into internal platforms.
• Implement logging, tracing, observability, and error-handling across systems.
• Collaborate with product, design, and platform stakeholders to turn business needs into scalable technical solutions.
• Help define engineering standards for reliability, maintainability, and deployment readiness.

Required Qualifications

• Strong hands-on experience building production systems with Python.
• Strong hands-on experience building modern frontend applications with React.
• Experience designing and consuming REST APIs and/or async service architectures.
• Experience with harness engineering, including building tooling for testing, validation, simulation, automation, or execution environments.
• Comfortable working across both application code and engineering infrastructure/tooling.
• Strong understanding of software design, debugging, and performance optimization.
• Experience with databases such as PostgreSQL, MySQL, or similar.
• Familiarity with CI/CD pipelines, Git-based workflows, and deployment practices.
• Ability to work independently, move quickly, and make sound engineering tradeoffs.

Preferred Qualifications

• Experience with workflow orchestration, agent-based systems, or automation pipelines.
• Experience with Docker, cloud infrastructure, and containerized environments.
• Familiarity with background job systems, queues, and event-driven architectures.
• Experience building internal platforms, QA tooling, evaluation frameworks, or developer productivity tools.
• Exposure to LLM/AI workflow orchestration, RPA, or test automation systems.
• Experience with observability tools, telemetry, and production monitoring.

What Success Looks Like

• You can ship polished frontend and backend features end-to-end.
• You can build robust harnesses that make systems easier to test, measure, debug, and scale.
• You improve both product delivery and engineering leverage.
• You help the team move faster by making complex workflows repeatable and reliable.

Ideal Candidate Profile
You are not just a feature engineer. You think in systems. You naturally ask:

• How do we test this?
• How do we simulate this?
• How do we validate edge cases?
• How do we make this reproducible?
• How do we instrument this so we can trust it in production?

You enjoy building the “glue,” scaffolding, and runtime support that turn promising ideas into dependable products.

The core of this role is production reliability and deployment ownership — keeping live systems stable, responding to incidents, and integrating AI models into scalable real-time infrastructure. Frontend work exists but is secondary: the team has a designer and uses AI-assisted tooling for UI iteration.

Responsibilities:
- Own deployment, environment management, and release workflows across Kubernetes-based, Railway-hosted, and other cloud infrastructure.
- Respond to production incidents, perform rollbacks, and restore service stability, including outside business hours.
- Deploy and operate AI inference services on GPU platforms such as Modal or RunPod and integrate them into real-time product flows.
- Build and maintain real-time communication and async processing flows, including LiveKit-based session infrastructure.
- Work with TypeScript / JavaScript and Python application code in production environments.
- Support database-backed product features, schema evolution, and migration workflows.
- Improve observability, logging, monitoring, and incident debugging workflows.
- Contribute to frontend and backend product functionality as needed, using AI-assisted tooling where appropriate.
- Maintain clear and up-to-date documentation for every product, service, and integration, including architecture diagrams, API contracts, deployment procedures, and environment configuration.
- Ensure every new feature is discussed, scoped, and agreed upon before implementation begins. No undocumented or uncoordinated changes to production systems.
- Collaborate with engineering and product stakeholders to clarify requirements, identify risks, and ship practical solutions.

Required skills:
- Strong hands-on experience with TypeScript (Node.js) and Python for production backend development.
- Solid experience with Kubernetes, Helm, and container-based deployment workflows.
- Experience with real-time systems: WebSocket-based communication, session lifecycle management, and event-driven flows.
- Experience deploying and operating AI inference services on GPU platforms such as Modal, RunPod, Replicate, or similar.
- Experience integrating LLM-based services, voice AI APIs, or media-processing pipelines into production systems.
- Experience debugging distributed or multi-service systems, including reading logs across multiple services and environments.
- Comfort with production ownership: incident response, rollbacks, and on-call responsibility.
- Solid understanding of backend APIs, service integration, and system design.
- Experience with PostgreSQL and ORM-backed schema management and migrations.
- Sufficient frontend experience to ship and deploy UI changes with AI-assisted tooling.
- Ability to work independently and bring structure to ambiguous technical situations.
- Strong written and verbal English communication skills.
- Experience using AI-assisted coding tools (e.g., Cursor, GitHub Copilot, Gemini) for faster development and iteration

Nice to have:

What we value:
- Strong ownership and reliability, especially in production.
- Pragmatic engineering judgment: shipping something stable beats over-engineering.
- Comfort with production responsibility and debugging under pressure.
- Ability to move across backend, infrastructure, and frontend without losing clarity.
- Clear communication, honest estimation, and practical execution.
- Documentation discipline: if it is not written down, it does not exist.

What we offer:
- Real impact: your content will directly attract new clients.
- Mentorship and growth.
- Freedom to experiment and test new formats.
- Flexible schedule and a remote-first culture.

About the Client
Our client is a UK-based company operating a live B2B SaaS multi-module platform which is already serving paying users. They are currently undergoing a structured transition from a rapidly AI-prototyped codebase (using Lovable.ai) to a production-grade solution — built for long-term scalability and maintainability.

Job Description
We are looking for a Senior React / Supabase / TypeScript Developer who will take ownership of refactoring and hardening an existing SaaS platform. The core product logic, UI, and data layer are functional — this is not a rebuild. The goal is to elevate code quality, architecture, and operational reliability to production standards.

Stack

• Frontend: React 18, TypeScript, Vite, Tailwind CSS, shadcn/ui, React Router.
• Backend: Supabase (PostgreSQL, RLS, Deno Edge Functions, Auth, Realtime).
• Payments: Stripe (subscriptions, webhooks, metered billing).
• Auth: Google OAuth via Supabase Auth.
• Deployment: Currently Lovable Cloud (migration to Vercel or similar is in scope).
• AI Layer: External LLM API calls orchestrated through Edge Functions (you won’t need to write prompts, but you will need to understand and refactor the function architecture around them).

Scope of Work
The engagement is structured across three sequential phases.
Phase 1 — Audit & Architecture Proposal. Full codebase audit with a written proposal and prioritised recommendations. Sign-off from the client required before proceeding to Phase 2.
Phase 2 — Refactor & Harden. Systematic refactoring of the frontend architecture, Edge Functions, RLS policies, Stripe integration, and performance optimisation.
Phase 3 — Testing & CI/CD. Test coverage for critical paths, CI/CD pipeline setup, staging and production environments, and technical documentation for team onboarding.

Engagement & Payment
This is hourly, project-based engagement. Phase 1 is scoped as a standalone paid deliverable — upon successful completion, we move forward with Phases 2 and 3.

Requirements

• Proven experience refactoring an AI-generated or rapidly prototyped React + Supabase codebase to production grade — mandatory.
• Strong expertise in React 18, TypeScript, and component architecture patterns.
• Deep hands-on knowledge of Supabase: RLS policies, Deno Edge Functions, Auth, and Realtime.
• Experience with Stripe billing integrations (subscriptions, webhooks, lifecycle events).
• Familiarity with Vite, shadcn/ui, Tailwind CSS, and React Router
• Experience setting up CI/CD with GitHub Actions and modern deployment platforms (Vercel or similar).
• English — B2+ (working proficiency required for client communication).
